Aspect: Somewhat bulldog-faced with a stocky body and pectoral fins that act as front paws. Changes colour according to environment, here yellow sponges. Population: Common, but rarely seen because of its extremely effective camouflage Notable feature: Carries a lure (see red arrow on picture below) retained above the front lip by a very thin filament. Here the lure actually looks like one of the white polyps of the nearby Halocordyle disticha (q.v.) hydroid. Environment: Generally hides amongst sponges, in not too deep waters Behaviour: Can easily be approached closely, so convinced it is that it has not been spotted.
